Optimisation mechanism for frequency reuse
First Claim
1. A method of network planning for a mobile network infrastructure comprising a switch site connected to a plurality of Hub sites that are connected to a plurality of radio base stations (RBSs) sites, wherein the mobile network is arranged to provide wireless data and voice services to access terminals in a way that the overall system quality is improved by improving the frequency reuse for said mobile network infrastructure characterized by, connecting the Hub sites to the RBS using combination of point-to-point links and point-to-multipoint links.

Abstract
The present invention describes a network planning mechanism for the optimisation of system quality associated with frequency reuse for a mobile network infrastructure and business access applications, by using an intelligent combination of microwave point-to-point and point-to-multipoint links in Broadband Wireless Access Systems or LMDS, for example. In an embodiment of the invention, Radio Base Stations (RBSs) sites can be connected to the Switch site by a combination of fibre optics, leased lines, or preferably microwave radio links. The embodiment enables traffic from several end sites to be concentrated at selected hub sites (hub site 1-4). The system is optimised by minimizing the quality degradation that can be experienced due to excessive interference inside a certain portion of the point-to-multipoint covered sector by means of the combined point-to-multipoint and point-to point solutions. The RBS, which on the planning phase will experience excessive interference in the direction to the hub, is not directly connected the point-to-multipoint hub, but through a point-to-point link connecting to an access terminal, co-located with a different RBS or business user, in line of sight with the previous one. The access terminal in turn connects the point-to-multipoint hub allowing a frequency reuse factor of one to be deployed.
